T0 all whom it may concern:

Be it known that I, GUSTAV TER MEER, a ctizen of Germany, residing at Hanover, Germany, have invented new and useful Improvements in Centriiugal Machines of which the following is a specification.

This invention 1elates to a centriugal machine more particularly designed or separating liquide 10m solid, fibrous er plastic mai;erials. The machine is provided with perforated walls, and with nevel and improved means 0r preventing the clogging of such walls.

In the accompanying drawings. Figure 1 is a vertica1 section of the operative part of a centrifugal machine embodying my invention; Fig. 2 a plan; Fig. 3 a section en a reduced scale on line A B Fig. 1; Fig. 4 a section on line OD Fig. 3; Fig. 5 a vertical seetion through the operative parts of a modification 0 the machine; Fig. 6 a bottomview, partly in section, 0 part of the same on a reduced scale; Fig 7 a side view of part of Fig. 6; Fig. 8 a section on line AB Fig. 5; Fig. 9 a vertical section through the operative parts of a further modification of the machine and Fig. 10 a partial section online A-B, Fig. 9.

In Figs. 14, the centrifugal chamber is formed by a pair of diverging perforated Wa11s a, b, an inner cylin drical slide er gate D, and an enter cylindrical slide E. Between walls a, b, is mounted a bail-shaped scraper c, which is provided With knie-edges opposte the walls, (Fig. 3). The scraper is adapted t0 oscillate ora certain distance, and during such oscllation, its knife-edges are adapted te move across the walls and thus clean the same of any adhering particles. Motion is imparted 130 the scraper rom the rotating hollow shaft d, of the machine, which carries gear wheel e. This Wheel, by pinion f, rotates an nternally toothed wheel q having inwardly extending peripheral projections h. These projections successively engage a lever z', influenced by spring Z, and mounted upon the shat k, of scraper c. By the means described, the wheel q, wil1 impart the desired oscillating movement to thescraper.

In use, the material te be d1ied ente1s through hol 10W shaft d, and open gate D, into the centrifugal chamber. By the rotation of the machine, the 1iquid is thrown 0ff thrbugh periorated walls a, b, which are kept open by the action of the scrapers c. After the mate rial has thus been sufliciently dried, gate D, is closed and gate E, is opened te discharge the material from the chamber by centrifugal action.

In Figs 5-8, the scraper c, has a series of inclined arme m, provided with sharpened edges that engage the diverging perforated walls a, b. Motion is imparted to the scraper from shaft (1, by belt n, that rotates worm 0. This worm engages worm-wheel 79, having a series of beveled inwardly extending projetions q. These projections alternately engage a pair of pins 1, of a lever 3, the a1bor t, of which turns in a hearing u. An arin 11/, of lever s, engages a corresponding n0tch 0n shait k, of scraper 0, so that the oscillating movement of the lever produces the desired reciprocating movement of shaft Ic, and consequently of scraper c.

In Figs. 9 and 10, the inclined perforated wall 1), is made in the orm of a rotatable disk which is engaged by the fixed cruciform scraper w. Motion is imparted to disk v, rom a worm rc fast en rotating shaft d, and engaging a worm-wheel y. A crank z, fast 0n shai't of wheel y, imparts, by link 12 and a crank ast en shat 13, of disk 1), the desired rotating movement t0 15110 latter.

I claim:

A centrfugal machine provided With a 110110w shaft, a communicating chamber having a. pair of divergng walls, one of which is perforated, a scraper engaging said wall, an inlet gate inteimediate the shaft and chamber, and an exit gate, snbstantially as specified.
